Three-point internal micrometer M312.233.M — digital, 12–16 mm range, IP65

The Three-point internal micrometer M312.233.M is a compact, workshop-ready instrument for precise internal and blind-bore measurement in fine‑mechanical and metalworking applications.

• Digital display with ABS/INC/UNIT functions
• Accuracy 0.005 mm for precise readings
• Measuring range 12–16 mm for small bores
• IP65 protection for workshop environments

Precision in confined spaces for consistent quality

The instrument delivers ±0.005 mm accuracy, achieved through a three‑point contact arrangement that centres reliably in small diameters and reduces alignment error. The compact 12–16 mm range classifies it among micro measuring tools for fine‑mechanical tasks where short anvils and low torsion are decisive. The clearly graduated measuring drum with scale and the digital display with ABS/INC/UNIT functions make reading and documenting values faster, reducing transcription errors during quality control and repetitive checks.

Built to endure regular workshop use

A matt‑chrome plated scale and vernier provide corrosion resistance and legible graduations, while hardened measuring faces ensure wear resistance at the contact points. The unit’s IP65 rating protects the electronics from dust and low‑pressure water jets, extending service intervals in machine shops. Supplied with a setting ring and extension (150×Ø11.7), the micrometer adapts to slightly recessed or awkward bores; the overall tool weight of around 1 kg balances stability and handling for one‑person operation.

Digital output and efficient data handling

Equipped with a data output RB 4.1, the device integrates into measurement chains or test benches for simplified data capture and traceable records. The display control set (ON/OFF/SET and ABS/INC/UNIT) enables immediate switching between incremental and absolute modes, supporting both manual checks and semi‑automated inspection routines. For workshop managers focused on throughput, the reduced reading time and direct data transfer improve process reliability and documentation efficiency.
